Dr Victoria Coleman is a Nanometrologist – a scientist working at Australia’s National Measurement Institute on accurate and precise measurements at the scale of a billionth of a metre. Her group works on the development of methods and measurement standards to support nanotechnology, with a strong focus on the characterisation of nanomaterials. Victoria uses atomic force and electron microscopes to image nanomaterials and is interested in exploring how visualisation and advanced image analysis methods can improve the accuracy of her measurements and the understanding of measurement uncertainty.
